Abstract

Objective

Dysregulation of WNT signaling plays a central role in tumor cell growth and progression. Our goal was to assess the effect of three WNT/β-catenin pathway inhibitors, Inhibitor of β-Catenin And TCF4 (ICAT), niclosamide, and XAV939 on the proliferation of primary cultures of human uterine leiomyoma cells.

Design

Prospective study of human leiomyoma cells obtained from myomectomy or hysterectomy.

Setting

University research laboratory.

Patient(s)

Women (n=38) aged 27–53 years undergoing surgery.

Intervention(s)

Adenoviral ICAT overexpression or treatment with varying concentrations of niclosamide or XAV939.

Main Outcome Measure(s)

Cell proliferation, cell death, WNT/β-catenin target gene expression or reporter gene regulation, β-catenin levels and cellular localization.

Result(s)

ICAT, niclosamide, or XAV939 inhibit WNT/β-catenin pathway activation and exert anti-proliferative effects in primary cultures of human leiomyoma cells.

Conclusion(s)

Three WNT/β-catenin pathway inhibitors specifically block human leiomyoma growth and proliferation, suggesting that the canonical WNT pathway may be a potential therapeutic target for the treatment of uterine leiomyoma. Our findings provide rationale for further preclinical and clinical evaluation of ICAT, niclosamide, and XAV939 as candidate anti-tumor agents for uterine leiomyoma.
